MANUFACTURE OF CARPETS AND THE LIKE.

Application filed October 17, 1916.

To all whom it may concern:

Be it known that I, HARRISON HORSFIELD, a subject of the King of Great Britain, residing at 46 WVoodside Crescent, Halifax, Yorkshire, England, have invented new and useful Improvements in the Manufacture of Carpets and the like, of which the following is a specification.

This invention chiefly relates to the manufacture of carpets and like looped fabrics and has for its object to produce a novel pattern effect due to the employment of mottle or parti-colored warp threads (hereinafter for convenience of description referred to as warp-yarns) twisted some in one direction and some in the opposite direction, without the employment of any pattern mechanism and without the printing or dyeing of the warp-yarns as in tapestry carpets.

Heretofore in the manufacture of woven fabrics it has been proposed to employ warps some of which are twisted in one direction and some in the opposite direction for the purpose of obtaining effects of light and shade, and it has also been proposed to heighten the effect by employing colored yarns.

Also it has been proposed, and it is well known, to employ mottle or parti-colored yarns, that is to say, yarns composed of two or more threads of difierent colors twisted together.

According to my invention these two methods are combined, that is to say, the beam is made up partly of warp-yarns twisted or folded from left to right and partly of warp-yarns twisted or folded in the reverse direction, and each warp-yarn is advantageously composed of three threads, these threads being of three different colors, or two of one color and one of another.

IVhatever may be the arrangement, the general effect in the woven fabric, having the warp-yarns arranged as above described, is a series of irregular zig-zag lines of color in the transverse direction of the fabric. If the oppositely twisted warp-yarns are placed alternately the result is that the zig-zags will be rather short and narrow while the result of grouping several warpyarns of the same direction of twist is that the lines of the zig-zags will be broad and lon 1% is to be understood that all the warpyarns of a beam need not be of the same Specification of Letters Patent.

character as regards coloring for example, certain of the warp-yarns might be composed of, say, two threads of light color and one of dark, while adjacent warp-yarns or groups of warp-yarns might have 'two threads of dark color and one of light.

A carpet having a pattern upon it produced by jacquard mechanism may have the ground or filling patterned as described.

My invention will be readily understood by reference to the accompanying drawing, in which Figure 1 illustrates a looped carpet fabric in which the beam is composed of groups of oppositely twisted waip-yarns.

Fig. 2 is a similar view wherein the beam is composed of alternate oppositely twisted warp-yarns, and

Fig. 3 is a view of a piece of fabric having a jacquard pattern upon it and a filling or ground composed of alternately oppositely twisted threads as shown in Fig. 2.

In all the above figures the zig-zag form of the pattern is most clearly seen by viewing the drawing in the direction of its length in a plane nearly parallel with its surface.

In these figures a a indicate the usual foundation warp-threads, I), 1) color warpyarns twisted from right to left, and 0, 0 color warp-yarns twisted from left to right. (Z, (Z are the weft threads for binding the color warp-yarns to the foundation warpthreads in a manner well known in the weaving .of carpets.

The fabric illustrated in Fig. 1 has alternate groups of four warp-yarns twisted from left to right and from right to left, and each warp-yarn consists of three differently colored threads which are indicated in black, white and hatch lines respectively.

The fabric illustrated in Fig. 2 is composed of alternate warp-yarns twisted in opposite directions, and each consisting of two threads of one color, indicated in white, and one thread of another color, indicated in black.

With the latter arrangement it will be seen that the zig-zag lines of the pattern are much shorter than in the arrangement previously described and that instead of the three colors being uniformly distributed as in Fig. 1, one color predominates, it will be noticed, however, that the general effect is the same.

In both of the above examples the folded or twisted Warp yarns can be run off a beam, comm'onto'them all, 1n a plain looml When manufacturing a fabric having a pattern 6 produced upon it. by jacquard mechanism, as shown, for example, in Fig. 3, it Will be obvious that the length of Warp threads a required for the ground or filling will vary according to the character of the jacquard pattern, and in this case therefore the iparti colored Warp threads must be run 05. creels orframes situated behind thej'acquard as usual;

.It islnot necessary that the pattern of a" fabric, ovenin accordancevvith this inven-' tion, should beof the same character throughout, as, for instance, the c'oloring'of the" vvarp yarns' in the diiierent groups may be varied, so that'theiabric, Whilepossess ='*in .th-e desired characteristic as to .the pat-- tern, Will be composed of groups of Warpyarns of varying shade or color; and again, thecentral portion of a carpet o'rfabric may have a; patternproduced as hereinbefore described, While the borders be Woven With any desired pattern in the ordinary manner; or. the center of a: .Width of fabric may be Woven With any desired design or patter-n, While the-borders-are provided with a pattern in accordance With my invention.

Claims: 1. A looped Woven fabric having a pattern produced by employing Warp-yarns 3. Ailooped Woven fabric composed of mettle: or part1-colored Warp-yarns twisted alternately in opposite directions, substantially as described.

l: In a looped Woven fabric-having a.- pattern upon it produced by jacquard mecha: nism, a ground or filling composed of particolored Warp-yarns some of which are twisted in one direction and the others in tl16 0ppOSlt direct-ion, substantla lly asdescribe I-IARRISGN HoRsrIELD.
